NITED STATES JAMES C. MITCHELL, OF LANCASTER, N. H., ASSIGNOR TOHIMSELF, JAMES A. SMITH, AND ALDEN R. TINKHAM, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 259,647, dated June 13,1882.

Application filed May 15, 1882.

To all whom it may concern:

Be it known that I, JAMES U. MITCHELL, of Lancaster, in the county ofCoos, of the State of New Hampshire, have invented a new andusefulImprovementinRailway-CarCouplings; and I do hereby declare thesame to be described in the following specification and represented inthe accompanying drawings, of which- Figure 1 is a top view, Fig. 2 afront elevation, and Fig. 3 a longitudinal section, of the draw-bar andfront portion of the body of a carprovided with my improved coupling.Fig. 4 is a top view of the coupling-link.

The nature of my invention is duly defined in the claims hereinafterpresented.

In the said drawings, A denotes a portion of the front end of a car,while B is a draw-bar below such.

The link-pin is shown at C as going down through the draw-bar and itsmouth, and provided with a pawl, D, the latter being hinged to such pinand shaped and furnished with a friction-roller, d, as represented. Thelink-pin, when at its lowest position in the draw-bar, is supported bythe head I) of the pin, which then rests on the top of the draw-bar. Inthe lower part of the flaring mouth 0 of the draw-bar is an inclinedplane, E, for the roller (Z to bear upon, and above the said inclinedplane and in the month of the said draw-bar is another inclined plane,F, whose purpose is to guide and force the link down to the plane E whennecessary.

The head b of the pin is grooved to receive the forked ends of twolevers, G, fulerumed to the car end portion A and arranged therewith, asrepresented. Each lever passes through one of two staples or straps, I,h'xed to the car, and provided with holes h to receive a pin, 1', tohold down the outer arm of the lever when it may be desirable to keepthe link-pin in a raised position.

Besides the levers, I have a chain, K, fixed to the link-pin and toreach to the top of the car, such being to enable a person on such top(No model.)

to raise the pin for uncoupling the car from another car.

The front end of the pawl D is inclined to the plane E. When a linkenters the mouth of the draw-bar the entering end of such link will beforced against the said inclined plane, and also against the saidinclined end of the pawl, and as a consequence the pawl will be moved upthe inclined plane, and in so doing will force the pin upward and allowthe link to pass underneath the pin and in rear of it far enough for thepin and the pawl to fall down Within the link and connect it with thedrawbar.

The levers are to enable the raising of the pin to be effected withoutthe necessity of a person going between the cars, whereby he would beliable to be crushed or injured in the process of coupling them.

Within the throatof the draw-bar is aspring, I, which, formed andarranged as shown, is to hold the link in a horizontal or properposition for it to entera draw-bar for coupling the latter to it. Thelink, in being forced into the draw-bar, passes under the spring, which,resting on the link while the latter rests on the bottom of the throat,holds the link in its horizontal position.

hat I claim as my invention is as follows, viz:

1. The combination of the draw-bar B, provided with the inclined planeE, with the linkpin C and the elevating-pawl D, hinged thereto, allbeing arranged and to operate substantially as set forth.

2. The combination of the draw-bar, provided with the two inclinedplanes E and F, with the link-pin and its elevating-pawl D, all beingarranged, adapted, and to operate substantially as set forth.

JAMES C. MITCHELL.
